Consequence of the Learning Curve in Direct Anterior Approach for Total Hip Replacement

Background:

Direct anterior approach to the hip (DAA) is being considered as one of the most promising minimally-invasive approaches in total hip arthroplasty (THA). Purpose of this study is to analyse influence of learning curve on clinical and radiographic outcome in direct anterior approach (DAA) for total hip replacement.

Methods:

The first 30 patients operated with DAA (group B) were compared to 39 patients operated by Hardinge approach (group A). Peri-and postoperative complications, Harris Hip Score (HHS), implant positioning, experienced pain and patient satisfaction were evaluated at a mean follow-up of 32 months.

Treatment and study plan

hip replacement

Procedure

Total hip replacement

Primary outcomes

  1. Clinical outcome of direct hip approach

    Time frame: 32 months

    Harry's hip score, a clinical score used in orthopedic surgery to describe outcome of hip function

Secondary outcomes

  1. radiological positioning of cup in the replaced hip

    Time frame: 32 months

    using standard x-ray of the hip placement of implants is measured in angles between the iliac line and component line for the cup

  2. radiological positioning of the stem in replaced hip

    Time frame: 32 months

    using standard x-ray of the hip placement of implants is measured in angles between the axis of implant and femoral axis
